Characteristics of the Male Sterile Phenotype of myb33 myb65.

(A) Flowers of the Columbia-0 ecotype photographed under bright-field microscopy.

(B) Flowers of the myb33 myb65 double mutant, photographed under bright-field microscopy.

(C) Three different bolts of myb33 myb65 that exhibit the sporadic setting of siliques, where the majority of siliques fail to set any seeds, but occasionally fully or partially filled siliques are set. Bolts are from plants grown at 22°C in a 12-h-day/12-h-night cycle and ∼90 μmol·m⁻²s⁻¹ light intensity.
